. IMPROVEMENT IN CARBURETERS.

specificationforming part of Letters Patent No. IS ,345, dated September 19, 1876 application .iile d November 18, 1875.

To all whom it mag concern:

Be it known that I, DANA Bioxnonn, of

the city, county, and State of New York, have invented certain new i and useful Improvements in Oarloureters and that the following is a full, clear, and exact description of the same, reference being had'to the accompanying drawings, making a part of this specification, in which-.-

Figure 1 represents a vertical section through the tank for containing the carbureting mate rial, and also through the saturating tank and mechanism. Fig. 2 represents a vertical section through a modified form of the containing and the saturating tanks or chambers and their appliances; Fig.3 represents averti cal section through a modified form of the tanks or chambers contained, substantially, one withinthe other. a Fig. 4 represents a vertical transverse section through the saturatingchamber, showing the float and itsappliances,

and the absorbent material in the chamber, as

in Fig. 3. Fig. 5 represents a plan of the under or chambered end of the saturator, with the absorbent materialin place. Fig. 6 rep resents a plan of the under or chambered end r of the saturator in spiral form instead'ofhaving concentric partitions, as in Fig.5. 1 Fig.

7 represents, in perspective, a top plan of the saturatingapparatus, as shown in Fig.5.

rial, aswill be explained. l

A, Figs. 1 and 2,:represents tanks for containingthe saturating material, which tanks, I are placed external to the tanks B, whichcon- M tam the saturating apparatus,;and connected thereto by a pipe, or. The saturatingappa ratus G is seen at Figs-5, 6, and 7, separated from its tank, and in working position, as seen at Figs. 1, 2,3,4, which are mere modijjications of each,0ther.. The saturating apparatus O \is of either. cylindrical, form, as seenyin Figs. 5 and 7 or it may be of a spiral. form,fas in Fig. 6. 1lneithercase its under side has; two walls, b b, lot a form correspond? 1 ing toeither the circularor spiral, asthe case may be, forminga chamber or passagac, .divided by radial walls (1, in which those care of perforated metal or wire-gauze, and those f, in Fig. 5, are solid, while all of the radial walls, as in Fig. 6, may be perforated or of wire-gauze. In the alternate chambers formed on the saturator, by the radial walls, sponge g or other absorbent material is placed. To the saturator G, as at Figs. 2, 4,, and 5, there is connected or combined a float, D, which, as

.at Fig. 2, serves two purposes, viz., to keep hydrocarbon, and may pass out through a pipe in the cover of themhamber B to the burners or gasometer. I n a At Fig. 2 the same general plan is followed out. The gas or air to be carbureted passes down throughan elastic pipe,j,' made bellowsfashion, thence through the branch pipes k k, and through the openings 2 2, into the saturator, as shown at Fig. 5, where,.as gseenby the arrows, the gas or air passing through the saturated sponges es'capes at twopoints, 3 3

and thenceout at l, to be used or stored, When the float D rises beyond a given point,

the rod or link "m closes the supply pipe or "cook, and, per contra, when the liquid gets too low in the chamber it opens said supply-cock. The pipe j, made ,as shown and of leather, works well, but other flexible material may be used. i At Fig. 3 l have shown the saturating apa paratus U as being inside of. the supplytank This, by some, is regarded as dangerous,

and the plans shown at Fig. I may .beusedtheair-tight tanks being external to the sat-; urator lh(l,lllf0ll6 case, quite remote from it. in Figs. 3and1 the oarbureting material may pass from the chamber A under the wall was at o inFig. 3, or through a,as shown in Fig. l, the current of, gasor air and the consump tion of the material in O inducing. thecarbu r.

At Fig. 4 is seen, also, the. saturator G inside of the'charnber B, which is also the saturating chamber in this case. The chambers A are airtight, or practically so. Where they are shown as having inlet and exit pipes, it'is with the perforated walls and .the absorbent arranged in said chambers prevent the es cape of the gas or air untilit is thoroughly suroharged with the carbureting material.

Having thus fully described my invention, what I claim therein as new, and desire to secure by LettersPatent, is-

2, 5, and 7, having outside walls I) b, sponge chambers and passages a, radial walls d,- and branch pipes 70, all constructed and arranged substantially as shown and described.
